Definition of emission spectrum in English:

emission spectrum


  • A spectrum of the electromagnetic radiation emitted by a source.

    Compare with absorption spectrum
    • ‘In this way, the mean relative intensities of the emission spectra were calculated to obtain an averaged emission spectrum for each species.’
    • ‘The gain or the stimulated emission spectrum should be spectrally similar to the steady-state fluorescence spectrum and show similar solvent dependence.’
    • ‘The collection of wavelengths of light emitted by hydrogen gas is called the emission spectrum of hydrogen, and there is a corresponding spectrum for absorption.’
    • ‘It is likely that both the absorption spectrum and the emission spectrum are changed at high intensities with respect to the low-intensity spectra of DsRed recorded by conventional spectrometers.’
    • ‘The position of the rose bengal emission spectrum in the trypsinbound state resembles the emission spectrum of rose bengal in neat acetone.’
    • ‘Then, comparing the companion's infrared emission spectrum with spectra calculated from models of gas giants, they concluded that the companion is most likely two to three times as massive as Jupiter.’
    • ‘This external cavity configuration allows the wavelength of the laser to be tuned across the broad emission spectrum typical of glass-host lasers by changing the prism angle.’
    • ‘In liposomes the excitation spectrum is shifted to higher wavelengths and the emission spectrum to lower wavelengths, typical of a fluorophore moving into a more hydrophobic environment.’
    • ‘First, the emission spectrum of the donor molecule must overlap with the absorbance spectrum of the acceptor.’
    • ‘The emissions are then analyzed and separated into an emission spectrum that is characteristic for each element.’
